of which the following is a specification.

This invention relates to improvements in nozzles for grease pumps suchas used at service stations for filling transmisslon gear housings ofautomobiles. I

The main object of the invention is to provide a nozzle formed to anchoritself in the filling opening of the gear housing, so that it isunnecessary for an attendant to hold the nozzle in said opening whilethe grease is being pumped into the housing. In addition, it is theobject of this invention to provide a nozzle capable of being locked Iwithin filling openings of various sizes, so that the locking featuremay be utllrzed 1n filling the ear housings of automoblles of various maes. I

In the annexed drawing forming a part of the following. specification:

Fig. 1 is a top plan view of the improved nozzle.

Fi 2 is an end elevation looklng toward the dlscharge end of the nozzle.

Fig. 9 is a sectional View taken on line 9-9 of Fig. 8.

Referring to the annexed drawings, the hose 1 leading from the greasepump is provided with a nozzle consisting of a rigid tubular memberprovided with an enlarged portion 2, adapted to be attached upon the endof the hose 1. Adjacent the attaching portion 2 the nozzle is providedwith a valve housing in which is mounted a rotary valve 3 operable bymeans of a lever 4 attached to the stem of the valve 3. The portion 5 ofthe nozzle adjacent the valve is cylindricaland the discharge portion 6of the nozzle is bent at an angle to the portion 5 and is conical,tapering towards the discharge end. The extension of the bend betweenthe portions 5 and 6 is at the top of the nozzle. On the top of theconical discharge portion of the nozzle is a longitudinal row ofuniformly s aced transversely extending arcuate lugs ,-8, 9 and 10, thelug 7 bein adjacent the discharge end of the nozz e and the lu 10 beingat the bend between the in termediate portion 5 and the dischargeportion 6 of the nozzle. The lug 8 is somewhat wider and higher than thelug 7 the lug charge portion 6 of the nozzle so that when the portion 6of the nozzle is inserted into a circular opening. with the bottom ofthe nozzle sliding on the bottom of the opening the largest lug whichwillpass through the opening will substantially conform to the upperportion of the circular opening. Opposite the lug 10 at the innerportion of the bend between the portions 5 and 6 of the nozzle is aspacing rib 11 adapted to engage the bottom of a circular aperture andhold the nozzle in a position in which the lug 10 is in lockingposition. On the sides of the' nozzle at diametrically opposite pointsadjacent the bend are horizontal centering and pivot forming lugs ortrunnions 12.- The number of locking lugs upon the discharge portion ofthe nozzle may of course housings of standardsizes. The lugs 7, 8,

9 and 10 are graduated to permit each to just pass through one of fourstandard openings.

In Fig 3 the transmission housing 13 has an opening 14 which will justreceive the smallest lug 7. When the conical end 6 of the nozzle hasbeen'entered into the opening 14 far enough to bring the lug 7 insidethe housing the nozzle is released and the rear end thereof drops bygravity fulcruming about the outer lower edge of the opening 1 1 andlifting the lug 7 into engagement with the interior of the housing abovethe upper edge of the opening and making it unnecessary for an attendantto holdthe nozzle in place while the grease pump is belng operated tofill the housing.

In Fig. 5 is shown the position in which the nozzle is held while it is.being inserted in the opening, the housing 15' having an opening 16through which the lug 8 will ust passJFig. 6 shows the nozzle in lockingposition in the opening 16.

In Figs. 7 8 and 9 is showna transmission housing 17 having the largestsize opening 18. In inserting the nozzle into the opening 18 the end 6of the nozzle is'turned downwardly as it is inserted so that the lug 10is brought within the housing 17 and the trun ni'ons 12 are broughtopposite the opening. The nozzle is then lifted bodily until thetrunnions 12, (the outer ends of which are curved) substantially fitWithin the opening with the lower edges thereof on a diameter of theopening as shown in Fig; 9. \Vhen the trunnions are so positioned theend 6 of the nozzle is swung upwardly bringing the rib 11 intoengagement with the bottom of the opening 18 and the lug 10 into seatingengagement with the interior of the housing 17 above the opening 18. .Inre- .moving the nozzle the nozle end 6 is swung down about the trunnionsas a center until the rib 11 is brough outside the housingpermittingthe-nozzle to drop until the lug 10 isbelow the top of theopening 18 permitting the nozzle to be withdrawn.

The lugs 7 and 8 are made relatively wide and of arcuate form to morefirmly hold the nozzle in place and to limit lateral movements of thenozzle in the opening during the filling operation, and the taperingform of the nozzle functions to close openings of different sizes. Thelocking lugs also extend different distances from the axis of the nozzleto permit locking engagement with the inner edge of the openingaccording to the size of the opening, and while this device has beenespecially designed for filling axle housings and different casings, itis not necessarily limited to this use but may also be employed withadvantage in filling gasoline tanks and other receptacles having fillingopenings of difierent sizes.
